Hello guys.

Is it  normal the vacuum pump has the connector, inlet, i dont know how to say it, loose?

 

Please check the video

Is that play in the connection normal?

and where does he pump suction air from?

It pulls air out of the brake servo, and any other connected vacuum 'motors', exhausting any air that it pumps into the cam cover via this non-return flap valve.

 

 

I would not expect that hose to be loose, it should not allow any air in except what comes through that pipe that you are moving.

Got it, perfectly understood, but i dont not understand why i have seen many Fabias here in so pristine condition but with that hose is loose, someone even told me that it pulls air by the hose connection and the excess sends it out by the surrounding (where it has the play)

If the pump exhausted air that way by design, I think a lot of oil would leak out of there too.

Yes, you are right, it makes sense.

 

So it pulls air instead exhaust

Thats why, while i solve the case i put this 

The fuel filter is just momentary,  i needed to see if there is oil contamination in the process.
